2ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ الاشْعَرِيُّ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ عَلِيٍّ الْوَشَّاءِ عَنْ أَبَانِ بْنِ عُثْمَانَ عَنْ أَبِي الصَّبَّاحِ قَالَ أَشْهَدُ أَنِّي سَمِعْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلام) يَقُولُ أَشْهَدُ أَنَّ عَلِيّاً إِمَامٌ فَرَضَ الله طَاعَتَهُ وَأَنَّ الْحَسَنَ إِمَامٌ فَرَضَ الله طَاعَتَهُ وَأَنَّ الْحُسَيْنَ إِمَامٌ فَرَضَ الله طَاعَتَهُ وَأَنَّ عَلِيَّ بْنَ الْحُسَيْنِ إِمَامٌ فَرَضَ الله طَاعَتَهُ وَأَنَّ مُحَمَّدَ بْنَ عَلِيٍّ إِمَامٌ فَرَضَ الله طَاعَتَهُ.
2. Al-Husayn ibn Muhammad al-Ash‘ari has narrated from Mu‘alla ibn Muhammad from al-Hassan ibn Ali al-Washsha from Aban ibn ‘Uthman from abu al-Sabah who has said that he heard Imam abu ‘Abdallah عليه السلام saying, “I testify that Amir al-Mu’minin عليه السلام is the Imam obedience to whom is obligatory by the command of Allah, that al-Hassan عليه السلام is the Imam obedience to whom is obligatory by the command of Allah, that al-Husayn is the Imam obedience to whom is obligatory by the command of Allah, that Ali ibn al-Husayn is the Imam obedience to whom is obligatory by the command of Allah and that Muhammad ibn Ali is the Imam obedience to whom is obligatory by the command of Allah.”
